Chemistry Question on Thermodynamics

Unit of entropy is : -

A

JK−1 mol−1JK^{-1}\,mol^{-1}

B

J mol−1J\,mol^{-1}

C

J−1 K−1 mol−1J^{-1}\,K^{-1}\,mol^{-1}

D

JK mol−1JK\,mol^{-1}

Answer

JK−1 mol−1JK^{-1}\,mol^{-1}

Explanation

Solution

ΔS=qT\Delta S = \frac{q}{T}
qq = required heat per mol
TT = constant absolute temperature.
Unit of entropy is JK−1mol−1 JK^{-1} mol^{-1}
